Adobe just released an Apache-2.0 licensed reference implementation of the OpenPBR Surface standard, extracted from their in-house Eclair renderer.
Neat trick: the reference implementation cross-compiles for C++, GLSL, Cuda, Metal, and Slang!

Screenshot showing skin with micro-occlusion at the top, and micro-shadowing below.
I finally wrapped up the second post on the series about micro-shadowing. On this one I go over a basic approach based on a microsurface, and I show results for different materials and lighting conditions.

lovely old article by @noelfb.bsky.social is on the-orange-site www.noelberry.ca/posts/making... love it! one thing that struck me (re)reading it was that your goal makes a HUGE difference: are u making your own game tools *to make a game you have in mind* or *to make your own game tools*
Real-time Rendering with a Neural Irradiance Volume
Delivering fast inference (~1ms/frame), a tiny memory footprint (1-5MB), 10x quality gains over probe-based methods @ equivalent mem budgets, bringing neural rendering within reach of consumer hardware without RT or denoising.

I'd like to share @daqilin.bsky.social and I co-authored a chapter in the latest GPU Zen 4 book.
We cover the engineering details of implementing ReSTIR GI & PT in UE5's NvRTX branch, adopted in NVIDIA's Zorah project showcased at CES and GDC last year.
The book is now available on Amazon.
🧵 I've been experimenting with caching the best lights in world space to improve NEE sampling. Inspired by ReGIR, MegaLights, and www.yiningkarlli.com/projects/cac....
Dear ImGui 1.92.6 released!

~80 fixes/improvements/additions
(incl. new default scalable vector font matching classic font, color markers on multi-components widgets, many fixes for fonts, tables, tree nodes, text input, navigation, viewports, backends...)

Interesting paper showing great results for replacing standard low-res rendering + temporal upsampling (DLSS) with high-res GBuffer + adaptive sampling. Makes sense given rising costs of lighting computations vs GBuffer. arxiv.org/abs/2602.08642
I've been working on something new since August 2025 and have decided to finally spill the beans:

Short conclusion of this Weekend project using Claude Code:
It currently feels like it's going to be more like this for the majority of people for at least the nearest future, butchering the lovely graphic from @mjwhansen.com:
I made a directional noise type I call Phacelle Noise which is pretty fast!
Is it new or does something functionally identical already exist? I'm not sure! But I didn't come across one like this yet anyway, so here's my findings:

This post shows how to get different constants for the R2 low discrepancy sampling sequence which have the same properties, but are smaller valued, so behave better in floating point at high sample counts.

The fact that the entire industry is now wasting time working on, integrating, analyzing, reviewing, and commenting on frame generation is so sad. Surely there are actually productive things we all can be doing instead.

My "How to Vulkan in 2026" @vulkan.org #Vulkan guide is now publicly available at www.howtovulkan.com
I still consider it a preview, though I'm mostly happy with it and only plan on changing minor things and incorporating some feedback.
This is a great introduction to differentiable / inverse rendering - rasterization specifically.
I've read through it and am currently working on implementing some things.
